Bio 1 River Ecology Lab Report Ecology is the study of relationships between organisms and their environment which includes both physical and biological factors. Humans have a major influence on ecosystems and this is very important in the waterways of California. The American River has been influenced greatly by humans by mining for gold‚ pollution through humans themselves‚ and an immense amount of other things (Becker 1992). We tested the growth of bacteria in the water of the American

Topic 3: Demecology – the ecology of populations The main idea: Note how mathematical models are used to examine variation in growth of a population. Lecture outline: 1. Statistic and dynamic characteristics of population. 2. Growth curves patterns: J-shaped curve and S-shaped curve 3. Population regulation: Density-dependent and density-independent factors. 4. Human population patterns: - Population numbers. - Demographic transition and structure - Population urbanization

In Mike Davis’s‚ Ecology of Fear: Los Angeles and the Imagination of Disaster‚ he analyzes the patterns and trends of Southern California’s environment. Through his research‚ Mike Davis explains how the history of Southern California’s environment proves that California is uninhabitable. However‚ over the last century there have only been two earthquakes and no one hundred plus year droughts. Leading to the question‚ how has man made it possible to live in such an environment? Over the past few

specifically‚ in ecology‚ as the predictable pattern of change in the species structure of an ecological community over time. There are two types of succession; primary and secondary. Primary succession refers to the successional development of plant communities that takes place on a site formerly devoid of vegetation and usually lack well developed soil. Secondary succession refers to the

between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from the German Oekologie or Ökologie) to describe complex systems of life both extant and extinct. These interactions
